Patrick Schwarzenegger goes casual in a t-shirt, swim trunks, and sneakers while heading out for lunch at Tra di Noi on Tuesday (May 13) in Malibu, Calif.

The 20-year-old actor/model was joined for the outing by his girlfriend Tootsie Burns and another pal.

Patrick is not only active in the entertainment world, but he is also an entrepreneur and college student. Earlier this month he opened up his latest business venture, a location of the build-your-own-pie chain Blaze Pizza at The Grove in Los Angeles.

“We went around and did a raise of capital,” Patrick told People. “It’s been my responsibility to oversee everything. I’m the owner, founder, pizza maker, pizza lover and anything else you want to throw on in there.”
